A new global campaign to persuade nations to ban “killer robots” before they reach the production stage is to be launched in the UK by a group of academics, pressure groups and Nobel peace prize laureates.

Robot warfare and autonomous weapons, the next step from unmanned drones, are already being worked on by scientists and will be available within the decade, said Dr Noel Sharkey, a leading robotics and artificial intelligence expert and professor at Sheffield University. He believes that development of the weapons is taking place in an effectively unregulated environment, with little attention being paid to moral implications and international law.

The Stop the Killer Robots campaign will be launched in April at the House of Commons and includes many of the groups that successfully campaigned to have international action taken against cluster bombs and landmines. They hope to get a similar global treaty against autonomous weapons.

“These things are not science fiction; they are well into development,” said Sharkey. “The research wing of the Pentagon in the US is working on the X47B [unmanned plane] which has supersonic twists and turns with a G-force that no human being could manage, a craft which would take autonomous armed combat anywhere in the planet.

“In America they are already training more drone pilots than real aircraft pilots, looking for young men who are very good at computer games. They are looking at swarms of robots, with perhaps one person watching what they do.”
